我有以下查询。将临时表插入到SQL Server中的递归查询问题

DECLARE @PartNo Char(22) 
DECLARE @PartIssue AS CHAR(4) 
DECLARE @Level AS INT

WITH Hierarchyct(BOMLevel,bmchild, parttype, bomparent, bmqty, leadtime, childissue,bmethod,rmethod, requiredqty) AS 
     (SELECT  @Level AS BOMLevel, 
         @PartNo AS bomchild, 
         @PartType as parttype, 
         cast('' AS CHAR(22)) AS bomparent, 
         cast(1.0 AS FLOAT) AS bomqty, 
         (SELECT stleadtim FROM stock WHERE stocknum = @PartNo) AS ldtime,

         (SELECT sm from partmaster where partnum = bom.bomchild) as parttype, 
         bom.bomparent, 
         bom.bomqty, 
         (SELECT stleadtim FROM stock WHERE stocknum = bom.bomchild) as ldtime,

         (SELECT eccroute FROM eccissue WHERE eccissue.eccissueno = (CASE WHEN LTRIM(RTRIM(bom.bomissue)) = 'CURR' THEN (SELECT drawissno FROM PartMaster WHERE PartNum = bom.bomchild) ELSE bom.bomissue END) AND eccissue.eccpart = bom.bomchild) as rmethod, 
         (bom.bomqty * hierarchyct.requiredqty) AS requiredqty 
         -- @CumLeadTime + leadtime as cumleadtime 
     FROM bom INNER JOIN hierarchyct ON bom.bomparent = hierarchyct.bmchild 


     WHERE bom.baltmethod =(SELECT eccbom FROM eccissue WHERE eccissue.eccpart = hierarchyct.bmchild AND eccissue.eccissueno = hierarchyct.childissue) 
    ) 


SELECT *

GROUP BY BOMLevel,bmchild, parttype, bomparent, bmqty, leadtime, childissue,bmethod,rmethod, requiredqty, stleadtim, sm, part 
--Where leadtime =0Mr1990 
) as temp

这工作得很好，但是当我试图让最终的结果到一个临时表（我需要这个运行光标）使用这个修改后的查询：

SELECT * FROM #CumLeadTimRep

我收到以下错误。

消息2714，级别16，状态1，行51
已经有一个在数据库中名为 '#CumLeadTimRep' 的对象。

Msg 156，Level 15，State 1，Line 62
关键字'as'附近的语法不正确。

试了很多，但没有得到修复。可能是什么问题？

加了他们，对不起，我忘了。 –

错误似乎相当自我解释....你正试图创建一个已经存在的表。要在使用'SELECT * INTO＃CumLeadTimRep'创建表之前纠正这个问题，只需添加一个检查来查看表是否已经存在，然后再尝试创建它 - IF IF OBJECT_ID（N'tempdb ..＃CumLeadTimRep'，' U'）不是NULL DROP TABLE #CumLeadTimRep;' – GarethD

找到了答案。问题是试图创建一个已经存在的表。正确的语法如下：
